Do you think the year 2015 will look like it did in Back to the Future, part two?

I have yet to see shoes that will tie themselves, holographic billboards, flying cars, or hover boards.

No, it's too soon, it will look very much like 2011, fashion will be slightly different prices slightly higher, 2015 is in 3 years time.  How has the world changed over the last 3 years?  Think back to 2008, that's roughly how far we've come which gives an indication of how much further we'll have come.

Not likely.

The really big changes to our sociaty will take another decade or two:

I think we could really do without flying cars. Earthbound ones are bad enough.

Cheers!
